Part 7/9:
One of the major issues with seed oils lies in their processing. While olive oil is typically cold-pressed, maintaining beneficial nutrients, most seed oils undergo severe chemical processing that strips them of their natural goodness. For example, canola oil is often extracted using hexane, a solvent with known health risks, leaving potential residual chemicals in the finished product. This processing not only diminishes the nutritional value but can also lead to harmful byproducts when oils are heated.
